application inea March 4, 190s. serial no. 419,194.

A Jr., a citizen of the United States, residing at F ruitvale, county ofAlameda, State of California, have invented certain newand usefulImprovements in VVave-Motors, of which the following is a specification.

My inventionl relate/sto means by which the tipping' or rocking motionproduced on a float, boat, or ship, by the action of the waves, isconverted into rotary motion; it w-ilzlibe more exactly understood byreference to the accompanying drawings, in Which- Figure 1 is a verticalsection of my machine on line fr-m of Fig. 2. Fig. 2 is a gian: view ofthe mechanism., `the deck of the oat being broken away- Fig. 3 isadetail view of knuckle-joint. Figui is a section of knuckle-joint onlinee-z o F ig. Fig. 5 isaI section 4and plan on line .fr-a2 of Fig. 4i. Fig. 6 is ai detaili of the governor and byepass valve connections.

My invention consists of a iioat, or boat, as 1,. on which'y isuniversally pivotedi, at 8, the hanging lever or pendulum 2 which hangsthrough an opening in the bottom of the float to any desired depths, andcarries on its lower end; the cross-arms or blades 3, the iiunction ofwhich is Jto-hold the pendulum still, or approximately so,as the floatis rocked by the wavesi This is done by reason @if the largey verticalsurfaces presented to the water iny all horizontal directions by theblades 3. The upper and lower edges of the cross aire sharp orknife-like, and ofii'er veryl little' resistance to the rising andfalling of the float.

'.Iihe'upper end of the pendulum above the fulcruni 8- is slidableloose' in a sleeve 4 which forms part of a universal knucklejoint. rEhesleeve is pivoted in a ring 5 which i-n turn is pivoted at right anglesto4 the sleeve pivots to the outside 'ring 6, through which are aseriesof holes Z (Fig. 3) for'the reception of the pins by which the pumppitmen 9 are connected up 'to thel pendulum. There are four of theseholes 7 1n= the present instance, but their ,number 'will vary with; thenumberlopumps used in the motor. -The parts 4:-5-6 constitute myuniversal*knuckle-joint or connections 'bet-Ween the' pendulum andv thepumpi pitmen.. l

The universal .Eulcrum'8 forv the pendulum or lever comprises a sleeveimmovably keyed or bolted to the pendulum, and which. sleeve is pivotedin a ring 8 similar to ring 5,.A and ring 5 being pivoted at rightangles to the sleeve pivots in the frame of the' float. Thus it is seenthat the pendulum has ai universal fulcrum accommodating the pendulum tothe tossing and tipping of the float inany and all directions.

The pitmen 9 are connected to. pistonsnol plungers within the respectivepump cylin ders 13 radially disposed around the u per end of thependulum. Thechambers ov the cylinders behind the pistons are connectedto a common source of fluidv supply contained in a conduit 17, and theyeach. discharge into a common outlet or exhaust pipe 18, leading to athree-cylinder engine 19, from .whose exhaust the duid is again ledbaclr through pipes 20--20a to reservoir 17 the top cylinder of theengine exhausting through pipe 20 to 17. The intake and outlet of theengineY are throughvalves 22 and 23 opened at the proper intervals byconnectingrods to an eccentric on the engine shaft, in a manner wellknown in the art.. The intake of each pump is through a respective valve241, and outlet 'through 25; these valves are automatic 1n action.

I have shown the motor in this instance as used in drivin-g a-multipolardynamo-26fnom which the electric current generatedmay be taken ashorethrough a cable and used ais desired. The speed of such a dynamo shouldbe high, and 'as nearly constant as ossible for the reason that theengine cyliin ers and the inlet and exhaust pipes and'A ports are all ofabout the same diameter, and, as the waves are slow in movement, thevolume of the. en-

ine cylinders is very much less than that of t e pumps, which will havethe eect of causing many turns of the engine at each slight movement01:' the pump plungers.. l A by-pass or shunt is provided at 27?, closedby stop-cock 28, acted: on by the' ball governor 29, which receives itsmotion throu h any suitable connect-ions, as 29, .from tie engine'.shait. The governor isset so' that the slowest, or least practical!movement of the plungers will run. the dynamo at its norableconnections, representedvat, opening said stepfcockaindf shunting. aiportion of* the Huid through pipe 27 to reservoir. 17, thus keeping thespeed of the dynamo constant. As shown in Fig. 6, the connections 30 comprise a slotted arm rigid with the governor sleeve and pivotallyconnected with the stem of valve 28.

ln usin my device as thus constructed, l

l prefer to ll reservoir 17 with oil, which may that no matter in whichdirection the tloatv roclrs or tips under the constant motion of theWares, the cross-arms will 'operate to maintain the pendulumapproximately perpendicular, and to anchor it against the relativemotion of the' float, so that the float is in the nature of auniversally fulcrumed le ver and acting through the universal jointvconnection with the pumps to keep one or more of the pumps continuouslyin operation to supply fluit pressure to the engine.

'Having thus described my invention, what l claim and desire to secureby Letters Patent is 1 l. lin a Wave motor, the combination of a floator buoyant body, a pendulum uL crumed 'thereon to swing in alldirections, and mechanism on the float connected to the pendulum bywhich the relative movements of the vfloat and pendulum with respect toone another are 'translated into rotary motion, said mechanismcomprising an engine and a part operated thereby.
